Much better than the first part in many aspects. A much bigger environment to explore, puzzles that really appeal to your creative thinking... Definitely liked it!
However, remarks like "puzzle solved" and "stone disc 3 out of 4" keep me from full immersion. Also, when you zoom in on an object, change a few things around, and then zoom out again, the object is shown in its old state. And last but not least: the music is mostly ok, but also really bad at times. Especially the song in "My 1st adventure" is really horrible, which, of course, is ingenious provided that this was done on purpose.
